Detailed Description

template<EnumFlag E>
class o2::utils::EnumFlags< E >

Classs to aggregate and manage enum-based on-off flags.

This class manages flags as bits in the underlying type of an enum, allowing manipulation via enum member names. It supports operations akin to std::bitset but is fully constexpr and is ideal for aggregating multiple on-off booleans, e.g., enabling/disabling algorithm features.

Example: enum class AlgoOptions { Feature1, Feature2, Feature3, }; ... EnumFlags<AlgoOptions> opts; opts.set("Feature1 | Feature3"); // Set Feature1 and Feature3. if (opts[AlgoOptions::Feature1]) { // Do some work. } // Check if Feature1 is set.

Additional examples of how to use this class are in testEnumFlags.cxx.
